ih all who/wit may concern:

Be it known that l, HENRY C. MILLER, a citizen of the United States,residing at Waterford, in the county of Saratoga and State of New York,have invented certain new and usetul Improvements inControl lingMechanism, of which the following is a specification-i.

This invention relatesto improvements in talking-machines, and moreparticularly the governor and stopping mechanism.

The prime object of the invention "is to provide a governor for atalking machine. may he set, previous to the starting or .machine, touniformly produce the selecrendered. archer object of the invention isto 'inpie and efiectual automatic stoppin the motor when the end .rcci1d groove'is reached.

The invention also relates to the specific ails of construction andarrangement of ts, all of which will be. hereinafter referred to andparticularly pointed out in the claims.

in the drawings: Figure 1 is a vertical section of a portion of a motorfor a talking machine, with my improvements applied thereto. Fig. 2 is aplan view of the same with the record support removed. Fig. 3 is avertical section illustrating a slightly difierent form of my invention.Fig. 4- is a detail plan view of the same. Fig. 5 is a similar view,showing the automatic stopping trip in normal position. Fig. 6 is adetail section of a slight modification.

The numeral l, indicates a frame from which depend hangers 2, supportinga shaft 3, carrying a motor 1, comprising a spring barrel 5, a worm gear(hand means for making the operation of winding the motor noiseless, thesame being indicated at 7. Depending from'the frame 1, is a hanger 8,formed at its lower end with an opening 9, pin 10, the upper end of thelatter being of conic-ail formation. The pin 10, is rigidly held inposition by a set screw 11. Supported on the conical end of the pin 10,-is a vertically disposed shaft 12, extending above the casing, andprovided at its upper end with atransverse slot- 13, below which arethreads 14;

A sleeve 15, is mounted on the shaft 12, and is threaded atits'upper'en'd at 16; to en gage the thread 14, on

the shaft, and it. is

ialso provided with a worm 17, with which the worm gear 6, meshes.Mounted near the upper end of the sleeve is a plate 18, having anenlargedportion 19, to iorni' a counterbalance, and a reduced portion toreceive a centrifugal weight 19, pivoted at 20. The plate l8-operates inan annular flange 21, extending upwardly from the frame 1, the interiorsurface serving as a track against which a friction strip 22, on theweight 19, contacts to retard the speed of the motor. Above the plate18', and mounted on the sleeve 15, is a record support 22, formed with acut out portion or way 23. Extending from the outside toward the centerof the record support and across the cut out portion 23, is a pin 2-i,held in place by a collar 25. The pin is threaded to receive a threadednut 26, designed to operate in the cutaway portion 23, and provided witha depending stud, to which is secured one end of a spring 27, connectedat its other end to a pin or stud 28, projecting from the weight 19. Theend of the pin 2%, extends beyond the periphery of the record support22, where it is knurled to provide a finger grip for adjusting thetension of the spring to regulate the centrifugal movement of the weight19. This part of the invention relates to the governing mechanism, andis constructed and arranged so as to make itncccssary to set thegovernor preceding the starting of the reproduction of a selection, andto thereby avoid irregularities in the piece being reproduced, so commonwith talking machines now in use. To increase the speed of the motor,the pin 24, is turned so as to move the nut 26, outwardly, whichmovement increases the tension of the spring 27, which obviouslyrequires greater speed of the plate 18, to throw the weight out- -wardlyin contact with thelfiange 21. To slow up the speed the pin 24, isturned in the opposite toward the center, which relieves tension on thespring 27, and thereby allows the weight 19f, to be thrown outwardlymore readily.

A boss or braking'surface 40, '(Fig. 1) depends from the frame "l, whichcooperates suitable Wearing. surface such as leather or the like beinginterposed between said two surfaces. This detail of construction isvthe direction to feed the nut- 26,

with adisk 41, carried bythe sleeve 15, a-

means I employ for stopping the motor at a 118 determined point, which,is automatic; controlled hy a tripping device actuated hy the stylus.

A cap d2, having a centrally disposed the upper end of the verticalshaft 12, the cross bill engaging the slot 13. An arr-n tends outwardlyfrom the cap and has pivoted to-it a lever -it%, having a stop 45, edved to contact with the arm on the can cause the two elements to movesimult-L' ously at the proper time,

The cap 42, and lever l are turned in direction of the arrow A, Fig. l,to dotted line positions through the cross and slot connection whichalso turns .shaft 12 and through the screw threads .l and 16 feeds thesleeve 15, and the dislr all, downwardly away from. the boss 48-; 'T'llever 44, is turned on its pivot until its end crosses the last end ofthe groove of t record 47. As the record is revolved it is the stylus48, toward the shaft 12, and WE? the last groove is reached it contactsv the free end of the lever 44, and causes Y turn on its pivot until thestop 45, with the arms projecting from the cap shown in full lines inFig. 4:. llHllllG this position of the parts is assumed th movement ofthe shaft 12, is retarded, hu"

being elevated by reason of the threads engaging the threads 14, untilthe disk c. contacts with the boss 40, which stops motor at the time theend of the record groove is reached.

The lever i l, can be set to accommodate records of any varying lengths,which make it possible to automatically stop the machine at the end ofany size record.

In Fig. 3, l have shown a slightly dill-3rent form of my invention whichonly differs from that shown in Fig. 1, in minor de l ofconstruction,however, the basis of 1:; operation is substantially thesazne. in this figure the shaft 50, does not more ve 'tically, but isformed with an internally threaded opening at its upper end, indicated5i, and a threaded pin 52, is fitted in said open-- ing. The pin 52, isprovided at its upper end with a slot 53, and a cap i2, suclraspreviously described cooperates with it. An opening 54, is formed in thecounterwei ht 19, and the shaft 50, through which passes a sliding dog55, the inner end oi which is of conical formation and is in the patho'lf movement of the conical end of the pin While its outer end isnormally in contact with the inner edge of the Weight 19. thisconstruction when the cap 492, is re volved it feeds the threaded pin52, down-- wardly, causing its beveled end to force the (log 5 outwardlyin contact with the weight, until the latter impinges the inner wall ofthe annular flange ill, thereby stopopening with a cross bar 43, isfitted over r or use ventiozs in ovei 101:, the operator lino dnecessary to re re nlayin a selroove The record sueport 22, is opening8, directly o W31 a co'onter-hnlence it and leads duct- 80,tot,liesleeve 15, and e 1135, or duct oil dropped cavity to 2 sleeve worm andhe lower out sleeve is n t :1 with passage down the outs the cup andends of the pi permitting of l i at l claim 1. ln combination, e shaving stationary ennui tor inciurlu he s:
